Thanks for the files.
Impulse.txt loads fine.
RTA.txt is missing phase but we’ll have an update out shortly to just load the magnitude.
Regarding SMAART control, a TF average is streaming fine from SMAART v8 to FIR Designer here. However all TF’s that are used in the TF Average and the TF Average need to be “Active.” Just check the “Active” checkbox for each TF in the SMAART Control “SMAART Measurements” list, or turn them on in SMAART itself.
